5-HT3 Receptor |
Quipazine dimaleate shows binding efficacy to 5-HT1 and 5-HT2 with Ki values of 230 nM[3]. Quipazine dimaleate displaces [3H]GR65630 from 5-HT3R in rat entorhinal cortex with a Ki value of 1.4 nM[3]. Quipazine dimaleate shows antagonistic properties on the rat vagus nerve with pIC50 value of 6.1, 6.49 and 6.17 for 5-HT2, 5-HT1 and inhibition of 5-HT release[4].

Animal Model:Male and female Wistar rats feed with different sources of the three macronutrients (Group 1: casein, corn starch, safflower oil. Group 2: egg protein, corn starch/sucrose, lard. Group S: casein hydrolysate, maltose dextrin, butter.)[1]
-
Dosage:2.5, 5 and 7.5 mg/kg
-
Administration:Intraperitoneal injection; 2.5, 5 and 7.5 mg/kg, one dose for once
-
Result:Increased water intake and food intake of male rats from Group S, and reduced food intake of female rats from Group 1 and Group 2s at 2h post-injection. Reduced food intake in female rats from Group 2, reduced protein intake in female rats from Group 1.

Solvent & Solubility
DMSO : 250 mg/mL (561.27 mM; Need ultrasonic; Hygroscopic DMSO has a significant impact on the solubility of product, please use newly opened DMSO)
Please refer to the solubility information to select the appropriate solvent. Once prepared, please aliquot and store the solution to prevent product inactivation from repeated freeze-thaw cycles.
Storage method and period of stock solution: -80°C, 6 months; -20°C, 1 month. When stored at -80°C, please use it within 6 months. When stored at -20°C, please use it within 1 month.

Select the appropriate dissolution method based on your experimental animal and administration route.
- For the following dissolution methods, please ensure to first prepare a clear stock solution using an In Vitro approach and then sequentially add co-solvents:
- To ensure reliable experimental results, the clarified stock solution can be appropriately stored based on storage conditions. As for the working solution for In Vivo experiments, it is recommended to prepare freshly and use it on the same day.
- The percentages shown for the solvents indicate their volumetric ratio in the final prepared solution. If precipitation or phase separation occurs during preparation, heat and/or sonication can be used to aid dissolution.
Add each solvent one by one: 10% DMSO 90% (20% SBE-β-CD in Saline)
Solubility: ≥ 2.08 mg/mL (4.67 mM); Clear solution
This protocol yields a clear solution of ≥ 2.08 mg/mL (saturation unknown).
Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (20.8 mg/mL) to 900 μL 20% SBE-β-CD in Saline, and mix evenly.
Preparation of 20% SBE-β-CD in Saline (4°C, storage for one week): 2 g SBE-β-CD powder is dissolved in 10 mL Saline, completely dissolve until clear.

Working solution concentration: 0.22 mg/mL
Method for preparing stock solution: mg drug dissolved in μL DMSO. Stock solution concentration: mg/mL.
1. Take μL DMSO stock solution;
2. Add μL .
